Now this is different. I got the original recipe from About.com. The original recipe calls for 3 cups of powdered sugar which is a lot, so I have changed some of the ingredients to suit my tastes. I dropped the amount down to two cups of sugar instead. It should still work. Also since I live at 5,000 feet less sugar is better. These brownies are rich and dairy-free. You can also substitute 1/2 cup apple sauce for the margarine if you want this to be lower in fat. And if you want less carbs, you can also replace the sugars with a sugar substitute.
